“…[1][2][3][4] For instance, the information on the volume change in piezoelectric materials, i.e., piezoelectric coefficient, is essential for design of actuators. 5,6 In some cases, the volume change can significantly influence the reliability of device performance such as the Li-ion batteries and gas sensors.…”

Size effect of cubic ZrO2 nanoparticles on ionic conductivity of polyethylene oxide-based composite Electromechanical (EM) response in ion conductive ceramics with piezoelectric inclusions was spatially explored using strain-based atomic force microscopy. Since the sample is composed of two dominant phases of ionic and piezoelectric phases, it allows us to explore two different EM responses of electrically induced ionic response and piezoresponse over the same surface. Furthermore, EM response of the ionic phase, i.e., electrochemical strain, was quantitatively investigated from the comparison with that of the piezoelectric phase, i.e., piezoresponse. These results could provide additional information on the EM properties, including the electrochemical strain at nanoscale. V C 2015 AIP Publishing LLC. [http://dx.

“…98 Finally, the SPM can be used as a moving current electrode, potentially extending well-known time domain electrochemical methods as PITT, GITT, and charge-discharge measurements, to the nanoscale. 99,100 The primary limitation of the SPM-based current detection is that the sum of ionic and electronic currents is measured. The use of ion-sensitive local electrodes (similar to liquid electrochemical SPM) to directly probe ionic currents in solids is limited by slow diffusion rates and large contact impedances that effectively limit spatial resolution to 10s of microns.…”

The Energy ChallengeThe last 10 years have witnessed dramatic changes in global civilization, including the impact of technological innovation on the level and quality of life and rapidly expanding middle class populations in developing nations. While these changes yield a broad range of positive outcomes, they also lead to the challenge of meeting the increasing energy requirements of the global society in a sustainable and environmentally-responsible manner. Indeed, energy and consequences of energy usage is one of the most important, and perhaps the most important, challenge facing humanity.The magnitude of the challenge can be seen in the estimates of future energy requirements. The US Department of Energy predicts that global energy requirements will increase over the 2008 values by 50% by the year 2035, Fig. 1. 1 The supply of this amount of energy will require drastic changes in the major energy sources, and increased attention to the environmental impacts.
